This is what I learned from the book "Stand Out Social Marketing" by Mike Lewis -
Social media sites, like Facebook and Twitter, push content away from the viewer very quickly. In the first hour after you post something on these sites, only 34% engagement was observed in 10 days, as compared to other sites like Flickr, which earned 82% engagement in 10 days. Also, Youtube, Flickr and WordPress
The best way to get your work out there is to build a landing page (website, blog) and drive traffic to it to maximize exposure. You can sign up for a free blog through Blogger. Directories such as Digg, Reddit, and Stumbleupon help drive additional views to your content.
Also, use Video (Youtube) and Photos to share with your readers.
